HEATING AND VENTILATING SYSTEM.

Application filed December My system relates to a heating system orfurnace, or stove, as is ordinarily used wherein fuel is being burnedwithin the central fire box having disposed therearound a shield toprevent an intensified heating Zone being created in the immediatevicinity of a heating plant, and has for its object the creation of auniform temperature within the room, or compartment to be heated and theventilating of the same.

A further object of my invention, conslsts in providing means for theinductlon' of a supply of fresh air from the exterior of thecompartment; selective means or shuttlng off the supply from theexterior and circulating the air to be heated withln the room itself. Ip 3 A further object of my invention consists in providing means forincreasing the draft of the vitiated air through or about the heatingstove and exhausting the same from the room, through suitable exhaustpipi 11g.

l/Vith these and incidental objects in view, the invention consists incertain novel features of construction and combination of parts, theessential elements of which are set forth in the appended claims, and toa preferred form of embodiment ofwhich is hereinafter shown withreference to the drawings, which accompany and form a part of thisapplication.

In the drawings Fig. l is a perspective view of one of my new andimproved heating devices, shown 1n position and connected to and fromthe exterior of the building, wherein the same is installed. r

Fig. 2 is a vertical cross section view through the heater illustratedin Fig. 1.

Fig. 3 is a cross section view, taken on line 33 of Fig. 2, looking inthe direction indicated.

Fig. 4 is a cross section view, taken on line 44 of Fig. 3, looking inthe direction indicated.

Like reference characters refer to like parts throughout the severalviews.

1 is the fire box, having a hinged fuel in-' let 2, disposed at the topof the fire box, the same being hinged by hinges 3. A draft controlinlet 4, is disposed at the front thereof and having a hinged closure 5,with means for admitting air therethrough. A smoke pipe 6, provided atthe top of the heater is adapted to carry away the products ofcombustion. A jacket 7 is disposed 15, 1925. Serial No. 75,511.

about the fire box and spaced apart therefrom as shown at 8. The bottom9 of the fire box extends beyond the fire. box and forms also a bottomfor the space'S, disposed between the fire box and the shell the samebeing shown at 10. A conductor pipe 11, connects the heating member withthe ex terior of the buildingand conducts freshair y from the exteriorof the building into the space surrounding the fire box and dischargesthe same between the fire box and the jacket ,7. I have provided'aheader at the end of the conductor pipe 11, having discharge outlets 11and 11 disposed at either end of the header and adapted to discharge thefresh air supply into the space between the fire box and shell 7, inorder'that the same may bring the fresh air, to be heated, in contactwith the fire pot at its lowest extremity; the header and the conductorpipe are connected by risers 13, for carrying the vitiated air into theheated space. A damper 12 is disposed in the conductor 11 to stop theflow of air from the exterior through the conductor 11 and an inletdamper l3, permits the inflow of air from the room to be heated into thespace disposed between the fire box and the shell; the object of whichis to permit a selective means for determining which air is to be heatedand whether the same is to be taken from within the room or from withoutthe room. It is a well known fact that warm air rises and the cold airfalls to the lower levels. It is also a well known fact that the heavierstratas of air are disposed within the lower levels. r

I am aware thatattempts' have heretofore been made for creating withinthe one heating element of a heater for the heating of the air withinthe, room without creating a highly heating zone and at the same time tocreate a, ventilating system thereby, by taking the colder stratas ofair from the lower level and passing the same from the room to be heatedto the exterior of the room; I am also aware that an induced drafthasheretofore been created and I am not claiming the invention broadlly,excepting in the specific manner in which Ibring about this result,which I do eiiieiently and economically. 1

The colder stratas of air are passed about the bottom of the stovearound the base jacket 14:, disposed about the base'of the fire box andflow onward into the exhau t pipe 15. This exhaust pipe 15, passes inthe immediate proximity of the heating zone, and between the fire boxand the shell, and the air passes therethrough becomes heated whichincreases the draft and permits of a greater volume of air beingexhausted therethrough. A damper 16, is disposed in the outlet pipe 17,to permit the manual regulation of the draft, or volumes of air beingpassed I therethrough.

While the form of apparatus herein shown and described isadmirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it isnot intended to confine the invention to the one form ofembodiment herein shown and described, as it is susceptible ofembodiment in various forms, all

coming within the scope of the claims which follow: 7

1. In a heating and ventilating system, the combination of a heater, anouter jacket therefor, and spaced apart therefrom, the

bottom ofthe heater being extended to and connected With the lower edgeof said jacket;

an ail conductor leading from an exterior point and teri'ninating inoutlets into the space between the jacket and the heater, at the bottomthereof, and an exhaust pipe having an inlet formed through the extendedbottom or the heater, and passing upwardly between the jacket and theheater to an exterior point. I

In a heating and ventilating system, the combination of a heater, anouter jacket disposed about said heater, and spaced apart therefrom, thebottom 01" the heater being extended outwardly to connect with the loweredge of said jacket, an air conductor leading from an exterior point andterminating at its inner end in outlets into the space between thejacket and the heater, and at the bottom thereof, means to regulate theflow of air through inlets formed in said conductor, and an exhaust pipehaving an inlet I formed through the extended bottom of the heater, andpassing upwardly between the jacket and the heater to an exterior point.
